ASTM RR:D04-1014 PDF Download

The ASTM RR:D04-1014 standard outlines the procedure for determining the resistance to plastic flow of bituminous mixtures. This test method is widely used in the asphalt industry to evaluate the ability of an asphalt mixture to resist deformation under load.

The standard specifies the equipment and materials required for the test, including the Marshall apparatus, molds, compaction hammer, and thermometer. It also provides detailed instructions on preparing the test specimens, which involves compacting the asphalt mixture at a specified temperature and density.

Once the specimens are prepared, the standard guides the tester in conducting the actual testing. This involves subjecting the specimens to a specified load and measuring the amount of deformation they undergo. The resistance to plastic flow is then calculated based on these measurements.

The ASTM RR:D04-1014 standard also includes information on reporting the test results, including the calculation of Marshall stability values and flow values. It provides guidance on recording and analyzing the data, as well as guidelines for determining the precision of the test method.
